What app is that you are using for those feeds and speeds? I need one of those for sure. I’m getting all jittery now. What fun.
Linked on the basics page.

Wait a sec. Looks like your WOC dropped on the last picture there.
I question the cutting force number I get though, as I didn’t have to put NEARLY the force it suggested. The cutting force is reffering to the horizontal pressure required to push the bit through the material?
I will have to look later, steppers will be here any minute.
Ryan, what cutting force do you feel is a general maximum you like to stay under on your lowrider. (I know, much more rigid then mine, but gives me an idea)
Not sure I will have to see my gcode that is loaded in it from the flat parts files, I like those numbers. That will give me real numbers, then maybe I can put those in the basics page under “advanced”…ahahah
I just got the steppers in so I am going to be busy packing orders for a while.
Sounds good, thanks Ryan. Did you happen to get some nice high torque ones for me? 
Gcode numbers, DOC, FR. I use stock settings, I have never needed more.
I suggest you just turn down accelerationa bit. You are running two times as fast as me. so slow your accel and you should be fone.
You should really go test some cuts with the calc. I really can;t reply for a few hours/tomorrow.
Sorry to but in, but where’s the ‘Basics’ page you mention?
Thanks
Matt
So after all this discussion has anyone made the parts for the nema 23 the only reason why i would use nema 23’s is because i already have them and will save me from buying new ones
I think I’ve seen them on thingiverse, but that may have been for the mpcnc, and not the lowrider. The only place I can see the 23’s being beneficial would be the Z steppers, and that’s only when folks are using full sized routers. Also something to think about, 23’s will most likely run hotter, so pla mounts might be a bad idea.
Yeah i have had a look on thingy nothing for the lowrider as yet i have started to make my own well not mine but modifying the original design to suit the nema 23’s i have managed to mod the x motor mount the z motors just need to have a 17 to 23 adaptor and in the process of moding the y axis motor mounts i hadn’t thought about heat so that could be an issue that i hadn’t considered
Ryan,
I know this reply is ancient, but did you ever follow up? Can you get equal (or lower) cutting loads with the 1/4" bits without setting your workpiece on fire or are there other gotchas that make it impractical/impossible.
If you can adjust your RPM you could be okay. There are people using all sorts of giant bits these days, even really big router V bits, and surfacing bits.
